My research focuses on rheology – the mechanics of how rocks and ice deform. Some of the overarching questions I pursue include:
- How well do the mechanical parameters in numerical models of Earth’s crust and glaciers reflect what actually happens?
- How long is the crust’s rheological memory?
- Is microstructure a significant control on strength in streaming ice?
I approach these questions using chemical and textural microanalysis, numerical models, geophysics (radar), geochronology, and, field observations. In addition to rheological questions, I am interested in applying microanalytical techniques to any suitable problem, within or outside the Earth and Climate Sciences. A list of some of our projects is on our geodynamics research group page.
I also co-manage our SEM laboratory, which consists of a Tescan Vega II XMU SEM with backscattered electron and cathodoluminescence detectors, EDAX Genesis EDS system with an Apollo40 SDD, and a TSL EBSD system integrated with the EDS system.
Finally, as an affiliate of the Maine Center for Research in STEM Education, which offers the Master of Science in Teaching degree, I am involved in education research and professional development, particularly as it relates to Earth and Climate Sciences.

ThermoElastic and Seismic Analysis (TESA) Toolbox Calculates the elastic response to changes in temperature and macroscale loading. Includes seismic anisotropy calculations and visualization.
Power-law Creep (PLC) Toolbox Calculates the viscous response to macroscale loading.
Seismic and Radar Toolbox (SeidarT) Calculates seismic and radar wave propagation. Designed initially for glaciology, this scale- and material-independent tool is applicable to any geological setting.
